Amorphous. The pudding can pass through an opening as narrow as 1 inch wide without squeezing.

Corrosive Body. A creature that touches the pudding or hits it with a melee attack while within 5 feet takes 9 (2d8) acid damage. A nonmagical weapon made of metal or wood that hits the black pudding corrodes after dealing damage, taking a permanent -1 penalty to damage rolls per hit. If this penalty reaches -5, the weapon is destroyed. Wooden or metal nonmagical ammunition is destroyed after dealing damage. Any other metal or organic object that touches it takes 9 (2d8) acid damage.

Spider Climb. The pudding can use its climb speed even on difficult surfaces and upside down on ceilings. 

Sunlight Sensitivity. While in sunlight, the pudding has disadvantage on attack rolls .

Ooze Nature. An ooze doesn’t require air or sleep.


Pseudopod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 9 (2d8) acid damage. Nonmagical armor worn by the target corrodes, taking a permanent -1 penalty to its AC protection per hit. If the penalty reduces the armor’s AC protection to 10, the armor is destroyed.


Split. When a Medium or larger pudding with at least 10 hit points is subjected to lightning or slashing damage, it splits into two puddings that are each one size smaller. Each new pudding has half the original’s hit points (rounded down).


The pudding lurks on walls or ceilings or conceals itself in shadows. It attacks creatures who venture into range and pursues the closest creature. It retreats only if exposed to sunlight, in which case it tries to climb away or squeeze into a crack.

Legends and Lore

With an Arcana or Nature check, characters can learn the following:

DC 10 Mindless and able to squeeze through the narrowest of cracks, oozes inhabit dank, dark places all over the world.

DC 15 There are many different types of oozes. Perhaps the strangest is the gelatinous cube: a nearly transparent ooze that engulfs dungeon explorers who stumble into it.

DC 20 Oozes dissolve any organic matter they come into contact with. Some oozes, such as black puddings, corrode metal as well.


A black pudding undulates along the ground and climbs walls, cresting and falling like a slow sea of oil or tar. When motionless, it resembles a dark pool of shadow and may be lost in an area of darkness. 

Black puddings devour living and dead organic materials, like flesh, wood, and bone, and melt metal as well. An adventurer who falls into a pool of black pudding leaves nothing behind but the gemstones of their jewelry.

A black pudding doesn’t shrink from swords or axes. When a black pudding is cut in half, it simply becomes two smaller black puddings.
